Caused by an interrupted flow of blood to the muscle of the heart. It results in the death of an area of heart muscle. A patient experiencing a heart attack feels a sudden, severe chest pain that may spread to the arms and throat.

The medical term for heart attack is myocardial infarction. A heart attack occurs when the blood supply to part of the heart muscle itself the myocardium is severely reduced or stopped. This occurs when one of the coronary arteries that supply blood to the heart muscle is blocked. The blockage is usually from the buildup of plaque (deposits of fat-like substances) due to atherosclerosis. The plaque can eventually tear or rupture, triggering a blood clot to form that blocks the artery and leads to a heart attack. Such an event is sometimes called a coronary thrombosis or coronary occlusion.

Heart attacks occur when an artery leading to the heart is blocked, and blood flow is slowed or stopped. The blockage stops the delivery of oxygen and nutrients to the heart, allowing cells to be damaged or even die. Heart attacks most often are caused by the blockage of an artery already narrowed by atherosclerosis.

Death of the heart muscle due to the loss of blood supply, usually caused by a complete blockage of a coronary artery, one of the arteries that supplies blood to the heart muscle. Death of the heart muscle, in turn, causes chest pain and electrical instability of the heart muscle tissue. Also known as myocardial infarction (MI).

(sometimes called a " coronary"): this is what happens when the supply of oxygen-rich blood flowing through one or more of the coronary arteries to the heart muscle is cut off. If the oxygen supply is severely reduced the heart can malfunction or cut out.

Also called myocardial infarction; results from permanent damage to an area of the heart muscle. This happens when the blood supply to the area of the heart is interrupted because of narrowed or blocked blood vessels. In the majority of cases this is due to coronary artery disease.

an acute event in which the heart muscle is damaged because of a lack of blood flow from the coronary arteries, typically accompanied by chest pain and other warning signs, but sometimes occurring with no recognized symptoms (i.e., "silent heart attack").

A heart attack occurs when the blood flow to a part of the heart is suddenly and permanently cut off, causing permanent damage to the heart muscle. Chest pain is typically severe and does not go away with rest or medicine that is effective with angina. Symptoms may indicate your heart is in danger many months or years before a heart attack occurs. Persistent symptoms, such as shortness of breath, nausea, great fatigue, angina/chest pain, fainting spells and gas-like discomfort - are red flags.

When arteries are clogged to the point of decreasing or stopping the flow of blood to the heart muscle, a lack of oxygen damages or kills heart muscle causing a heart attack. Recognizing symptoms and getting prompt emergency treatment can eliminate, prevent or limit the amount of heart muscle damage.

also know as an MI (myocardial infarction). Scarring or death of heart muscle due to lack of oxygen. Oxygen-rich blood is blocked by a blood clot in a coronary artery, usually due to plaque-related narrowing of the artery.

A nonspecific term usually referring to complete blockage of a diseased coronary artery by a blood clot, resulting in the death of the heart muscle cells supplied by that artery. 'Myocardial infarction' is a more specific term for what is usually meant by 'heart attack.'

This is caused by a small clot of blood that blocks an artery which supplies blood to the heart. The symptoms are sudden severe chest pain, sweating, pallor, breathlessness, and palpitations or simply collapse. www.BBC.co.uk/health/first_aid_action/flas/es_flash_heart_popup.shtml

When one of the coronary arteries becomes blocked by a blood clot and part of the heart is starved of oxygen. A heart attack usually causes severe pain in the centre of the chest. The pain lasts for more than 15 minutes, and may last for many hours. The pain usually feels like a heaviness or tightness which may also spread to the arms, neck, jaw, face, back or stomach. In some cases the pain may be mistaken for indigestion. There may also be sweating, light-headedness, nausea or shortness of breath. A heart attack may cause the rhythm of the heart to become disturbed. Sometimes a heart attack is 'silent' and produces little discomfort. It may even remain undiscovered until a medical examination.

Heart attacks occur when a coronary artery is completely blocked and a portion of the heart muscle is left without a supply of oxygenated blood. If the portion is large enough, the heart attack may be deadly.

also called myocardial infarction (MI), this occurs when an artery that feeds the heart becomes blocked. As a result, blood does not get to some parts of the heart and some of the heart tissue dies. The symptoms may include nausea, shortness of breath and/or pain in the chest, arm or neck.

The death of heart muscle due to the loss of blood supply. The loss of blood supply is usually caused by a complete blockage of a coronary artery, one of the arteries that supplies blood to the heart muscle. Death of the heart muscle, in turn, causes chest pain and electrical instability of the heart muscle tissue. See the entire definition of Heart attack

Death of an area of heart tissue due to a blockage of blood flow to the heart muscle (myocardium). Symptoms may include nausea, shortness of breath, and pain in the chest, arm, or neck. Also called myocardial infarction.

Also known as myocardial infarction (MI), this occurs when a portion of the heart muscle loses its blood supply. Symptoms vary, but may include: chest pain, nausea, vomiting, sweating, shortness of breath, palpitations, and/or dizziness.

Sudden, severe chest pain that occurs when a portion of the heart no longer receives oxygen-rich blood, usually due to total or near-total blockage of a coronary artery by a blood clot formed in an area already narrowed by plaque. The surrounding heart muscle dies and the heart stops working effectively. Also called a myocardial infarction (MI). Heart attacks are part of the acute coronary syndrome.

Also called a myocardial infarction. A condition related to heart disease in which the bloodflow to the heart is severely limited. In the most common scenario of a heart attack, a plaque in an artery that feeds the heart ruptures and triggers a blood clot, which deprives the heart muscle of oxygen.

Heart attack is a udden interruption or insufficiency of the supply of blood to the heart, typically resulting from occlusion or obstruction of a coronary artery and often characterized by severe chest pain. A heart attack is permanent damage to the heart muscle caused by loss of blood flow to the heart. A heart attack occurs when a clot or spasm blocks an already narrowed coronary artery. Left without oxygen, the portion of the heart muscle served by the blocked artery is injured (from WebMD).

also known as a Myocardial (of the heart muscle) Infarction, or M.I. This is death of a bit of heart muscle caused by blockage of the blood supply to that bit of muscle resulting in sudden severe chest pain, which may spread to the arms and throat.

Damage to the heart muscle caused when the blood vessels supplying the muscle are blocked, such as when the blood vessels are clogged with fats (a condition sometimes called hardening of the arteries).

The medical term for a heart attack is myocardial infarction (MI). This refers to the formation of infarcts (areas of local tissue death or decay) in the myocardium (heart muscle). Infarction occurs when the blood supply to an area of the heart is cut off, usually as result of a blood clot that blocks a narrowed coronary artery. Depending on the size and location of the areas affected, a heart attack may be described as mild or severe, but it always involves some irreparable damage to the heart.

A sudden closure or blockage of one or more blood vessels to the heart, cutting off the oxygen supply and causing damage to part of the heart. The term specifically refers to death of heart muscle cells, which is usually due to the blockage of a coronary artery.

A medical emergency that occurs when a blood clot forms suddenly in a heart artery and causes a blockage, usually after the surface of cholesterol plaque in the artery breaks. A heart attack, also called a myocardial infarction, usually produces chest pain and shortness of breath. It may also cause sudden death. If nothing is done to reopen the blocked artery, the heart muscle will die and be replaced by scar tissue. More than one million heart attacks occur every year in the United States; it is the leading cause of death from heart disease. Most of these deaths occur outside the hospital.

Heart Attack is Krokus' tenth studio album, and is described by the band as "The last attempt to keep the band together in a deep crisis"http://krokusonline.seven49.net/seven49.asp?IDCMainActiv=4560&CathActiv1=138&CathActiv2=676&IDCMainQueue=. As well as being the band's first album on MCA Records, it saw the return of old Krokus founding member Chris Von Rohr. The track Rock 'n' Roll Tonight was a live hit, and is still played by the band in concerts.
